  • Publication number: 20140020250
    Abstract: A method to ascertain measured friction torque to a bearing and a method to reduce preload variation of a hearing pair or set. Friction torque of a bearing is measured at a known load and speed. The value of the measured friction torque is then printed in a data matrix that is then applied to the bearing that was measured. Prior to assembling the bearings on a shaft system, the data matrix is read. The targeted friction torque is calculated for the shaft system based on the desired assembly preload. The bearing preload is then set and verified by measuring the friction torque of the pair of bearings assembled on the shaft. As a result of the method, bearing friction torque variation is substantially mitigated.

  • Publication number: 20130259414
    Abstract: An angular contact bearing is provided having an outer and inner bearing rings, and a plurality of ball rollers arranged between the bearing rings in two rows having a same reference circular diameter. The ball rollers in each row are held by a respective bearing cage. The ball rollers all have a same or different diameter and each of the ball rollers has two respective lateral faces arranged parallel to one another which are flattened symmetrically from a spherical basic shape and run with running faces in respective groove-shaped raceways defined in an inner face of the outer bearing ring and in an outer face of the inner bearing ring. The raceways have pressure angle axes pitched at a pressure angle with respect to a bearing radial axis. Adjacent ones of the ball rollers of the two rows are spaced apart to exclude mutual frictional contact. An assembly method is also provided.

  • Patent number: 8360653
    Abstract: Double row angular contact ball bearing (10) has split inner rings (18, 24) and two plastic comb snap cages (32, 44). The comb cage has retaining tabs (38, 50) which mate with retaining grooves (22, 28) in the split inner rings. These retaining tabs hold the inner rings into the bearing.

  • Publication number: 20120308172
    Abstract: The double row, tandem, angular contact ball bearing assembly uses snap cages for both rows of ball bearings. The use of snap cages reduces straddle between the rows and allows for improvements in spacing and increased load carrying capacity without increased outer dimensions of the bearing.

  • Publication number: 20110088502
    Abstract: A vehicle steering column assembly for transmitting steering movement from a steering wheel of a vehicle steering system. The assembly includes an integrated shaft bearing that connects to the steering wheel at one end, a tube assembly interconnected with the integrated shaft bearing at its other end, a yoke assembly having a shaft and being adapted to be interconnected with a lower steering component of the steering system, and a bearing assembly disposed within the tube assembly and around the shaft to support the shaft in axial sliding movement within the tube assembly.
